Create a class named Dot that contains a public method named ShowDot. The method should take no parameters. The class contructor should take a CancellationToken and a ManualResetEvent as parameters and save them into class fields.

The ShowDot method is to be run in a separate thread. The method must ensure that when cancel is signaled in the cancellation token, the thread is interrupted. Then, as long as cancellation is not requested, the thread should repeatedly wait on the manual reset event, write a dot ('.') to the console and then sleep for 1 second. If the thread is interrupted, it should exit (end).

Create a class named Dash that contains a public method named ShowDash. The method should take an object parameter that contains a CancellationToken and a ManualResetEvent (passed using a tuple).

The ShowDash method is to be run in a separate thread. The method must ensure that when cancel is signaled in the cancellation token, the thread is interrupted. Then, as long as cancellation is not requested, the thread should repeatedly wait on the manual reset event, write a dash ('-') to the console and then sleep for 3 seconds. If the thread is interrupted, it should exit (end).

The main application should create a CancellationTokenSource and two ManualResetEvent objects.

Then the main application should create an instance of the Dot class passing the cancellation token and one of the manual reset event objects to the constructor. The application should then create a foreground thread to run the ShowDot method and start it running.

Then the main application should create an instance of the Dash class. The application should then start the ShowDash method running using a thread pool thread and passing the cancellation token and the other manual reset event object to the method.

Once the threads are running, the main application should get a key from the user (use Console.ReadKey so the user does not have to press ENTER). If the user pressed a, the appication should set the dot manual reset event. If the user pressed s, the application should reset the dot manual reset event. If the user pressed z, the application should set the dash manual reset event. If the user pressed x, the application should reset the dash manual reset event. Finally, if the user pressed q, the application should signal cancellation for the threads and exit. The application will continue getting input from the user until q is pressed.
